چکیده
In this study, samples of 420 stainless steel were obtained by hot pressing from powder at temperatures 1,100 to 1,200°C. The aim was explore the influence processing temperature on their grain size, microstructure, densification and mechanical properties. results showed that it is possible produce dense these sintering temperatures. influenced density, structural phases, hardness samples. Martensite austenite present in sintered 1,100, 1,150, 1,180°C. Precipitation Cr23C6 observed after This sample one with highest density (99.7% densification) (771.9 HV).

Duplex stainless steels (DSSS) have a microstructure composed of ferrite and austenite phases that gives them a very good combination of mechanical and corrosion properties. These steels are desirable for many applications in the chemical and petrochemical industries. In the present study, a type of stainless steel was cast, solution annealed at 1200°C for 60 min and then quenched in water. Ini...
